Python Using Databases in Python Gettin' CRUD-y With It CRUD: Create Function

Posted by Alex Crump-Haill

I have no idea how to work this CRUD challenge as you can see. Can anyone offer clarification as to why this is wrong?

At the beginning of the challenge, a model 'Challenge' has already been imported. Does this mean that there is no point in setting up the variables again? I set them to None as I didn't know what to do but thought there was no point resetting the variables. When the start of the question talks about taking arguments, is this an allusion to putting them in the function's starting parenthesis (i.e. to take them as arguments)? Also didn't know how to set the steps default value to 1 other than in the parenthesis but this didn't work either as: def create_challenge(name, language, steps(default=1)) - it just read as syntax error. Didn't get the bit where it asked to create Challenge from the arguments?! Why would I need to reconstruct Challenge if I had already imported it from models? I basically don't get the whole thing.

crud.py 
from models import Challenge

def create_challenge(name, language, steps):
    name = None
    language = None
    steps = None(default=1)

    if name:
        Challenge.create(content=name)

:point_right: You don't want to reassign the incoming arguments before you use them.

It seems the whole point of this function is to provide a version of the .create method that supplies a default for steps.

Here's how I did it:

def create_challenge(name, language, steps=1):
    Challenge.create(name=name, language=language, steps=steps)
